(a) Averaged standard, deviant and MMN responses to duration (red), left gap (yellow), right gap (green) and interaural time difference (blue) stimulus paradigms, recorded from the CZ channel for control group (grey) and schizophrenia patients (colour). Individual subjects are denoted using dotted lines. Shading illustrates the standard error of the mean. (b) Balanced classification accuracy distributions for each stimulus paradigm with respect to measured response (MMN, standard and deviant). The number of samples with a particular accuracy level are represented with increased colour intensity. Medians of each set are indicated using horizontal lines. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
